Soils of the Past
A student-friendly textbook that describes ancient soils, how they may be identified, and their use in paleoenvironmental reconstruction Ancient soils contain vital mineralogical, geochemical, textural, and paleontological information about the continental environments in which they formed. Advances in isotope geochemistry and sequence-stratigraphic models allow evermore detailed reconstructions of environmental change from paleosols, and new insights into such diverse topics as atmospheric chemistry, global change, paleoecology, geobiology and mass extinction. This book educates readers about the field of paleopedology and how it remains a key area of investigation for geologists and enviro...

Soils of the Past
Landscapes viewed from afar have a timeless quality that is soothing to the human spirit. Yet a tranquil wilderness scene is but a snapshot in the steady stream of surficial change. Wind, water and human activities reshape the landscape by means of gradual to catastrophic and usually irreversible events. Much of this change destroys past landscapes, but at some times and places, landscapes are buried in the rock record. This work is dedicated to the discovery of past landscapes and their life through the fossil record of soils. A long history of surficial changes extending back almost to the origin of our planet can be deciphered from the study of these buried soils, or paleosols. Some rudim...

Beliefs that Bias Food & Agriculture
The book answers 10 questions addressed to the author in various forms. Some are personal, while others relate to global issues. All are answered with candor and detailed explanation. The answers will not suit those who seek confirmation of popular viewpoints, nor will they suit those who insist they are doing good without having knowledge of what they are really doing. But they will admirably suit those extremely important persons from all walks of life who are open to new knowledge, who can accept challenges to their beliefs and received knowledge. The answers cover such topics as: - why livestock are critical to food security - why free trade and markets can't solve food shortages - why aid shouldn't insist poor countries follow our model - how to reconcile science and commerce with popular ideals - how gross domestic happiness can be a serious topic - how more food can be produced with less land and fertilizer - why labels like Buddhist and vegetarian confuse life - what traditional wisdom is critical to development - how misrepresentation fuels fears about climate change - why small farmers and foreign agribusiness must coexist
The Dead Sea
Located 400 meters below sea level, at the tectonically active irregular boundary between the Mediterranean and Arabic plates, the Dead Sea is the site of many interesting phenomena. It provides a modern analog for ancient pull-apart basins and allows researchers to examine the process of evaporite deposition from deep water. It also offers insight into the adaptive ability of the life form living in the hypersaline brine. This book, based on a conference held in Tel Aviv in December 1993, focuses on the geophysics, geochemistry, hydrology, and climatology of the Dead Sea region.
